Figuring our a replacement transistor.

[Xdevo1973]

I am trying to replace a driver transistor in a small amp. One channel went out. I switched the driver transistor from the other channel and it came back. The print looks like FR52. Here are the readings from the good one. Can someone recommend one with similar readings?

Can you take a good legible pic of the transistors face?

What is it in?

You didn’t really give us any info! Model number? Picture of transistor?

Not close enough to read, also if this lettering is not eligible maybe the other channels is.

Also what are you fixing? That is the units model number and brand.

It is in this- a 1970s stereo made in the UK with a 10 watts maximum per channel amp. A very obscure brand. Elizabethan LZ212View attachment 3831412

Funny, this disc/radio/aux selector is a combination of two switches. Same is on my Sugden A21 mk3

Maybe you can use a BC327-25, observe maybe pinout to be different.
